1. Initial Assessment & Audit

Before beginning a migration, it’s essential to understand the full scope of your existing digital infrastructure. This includes analyzing the structure of your current CMS, content organization, integrations, and any third-party tools. At AashroTech, we begin with a comprehensive technical audit. This includes assessing URL structures, metadata, internal linking, user roles, backend workflows, content types, media libraries, and SEO-critical components. The goal is to document every detail of your current setup to ensure nothing is lost during the migration. We also assess pain points and inefficiencies that TYPO3 can resolve.

2. Defining Goals & Strategic Planning

Every successful migration begins with a clearly defined set of goals. Are you looking for better backend usability? Do you want to enhance mobile responsiveness, improve security, or upgrade your site's scalability? These objectives guide the roadmap we build. Our team creates a migration strategy that includes task distribution, deadlines, stakeholder involvement, and resource planning. This phase also includes identifying opportunities for automation, version upgrades, or UX improvements within the TYPO3 framework.

3. TYPO3 Setup & Environment Configuration 

Next, we prepare a robust development environment tailored to your TYPO3 version requirements. Whether it's TYPO3 v11 LTS or the latest v13, we configure your server (Apache/Nginx), install PHP with required extensions, and set up MySQL/MariaDB databases. We also integrate Composer for dependency management and Git for version control. Our environment setup includes staging and production environments, security hardening, caching configurations, and deployment pipelines—ensuring reliability and scalability from day one.

4. Theme Design or Template Integration

Whether you're using an existing design or starting fresh, we ensure your site's frontend is modern, responsive, and accessible. Our design team can create a custom Fluid template from scratch or convert your existing HTML/Bootstrap layout into TYPO3-compatible templates. We follow mobile-first design principles and make sure every element is SEO-friendly, WCAG-compliant, and optimized for fast load times. We also ensure that templates are modular and can be reused across multiple pages or layouts.

5. Content Migration & Reorganization 

Content is the heart of any website, and its accurate migration is critical. We analyze all content from your existing CMS—including text, images, media files, PDFs, and metadata—and organize it for seamless integration into TYPO3's page tree and content elements. For large sites, we use migration scripts and API-based transfers. We also ensure multilingual content, structured data (e.g., FAQ schema), and SEO meta tags are preserved. Content is validated to match original formatting and tested for display accuracy across browsers.

6. Functional Migration & Extension Development 

From contact forms and search tools to complex booking systems or custom eCommerce features, we handle all functional aspects of migration. We analyze the existing feature set, map it to TYPO3 equivalents, and either install third-party extensions from the TYPO3 Extension Repository (TER) or build custom solutions. Using Extbase and Fluid, we write modular, upgrade-safe extensions. Where possible, we enhance functionalities—adding backend controls, dynamic filtering, or AJAX capabilities to enrich user experience.

7. Testing, QA & Device Compatibility 

Thorough testing is essential to ensure a seamless post-migration experience. We create test cases for every feature, form, and page layout. Testing includes:

• Functional testing for form submissions, login areas, and dynamic modules.
• Responsive testing across devices and screen sizes.
• Browser compatibility testing (Chrome, Firefox, Safari, Edge).
• Accessibility checks and performance audits using tools like Lighthouse.

Bugs or inconsistencies are logged and fixed before the final deployment.

8. Launch & Post-Migration Setup 

Once the site passes all QA tests, we prepare for go-live. This includes configuring the production environment, updating DNS records, setting up redirects from old URLs (to maintain SEO), and enabling caching strategies. We closely monitor the live environment for anomalies. Our team remains on standby for post-launch support during the critical first few weeks. This guarantees a smooth transition without affecting user experience or organic traffic.
